  • the present invention relates to products used for treating, cleaning and polishing stone elements. More in particular the invention relates to a cleaning composition for stone materials of natural and artificial origin
  • the cleaning of exposed stone material surfaces is mainly carried out through mechanical processes such as the process of "sandblasting", or through the use of acids.
  • sandblasting With regard to the process of sandblasting, it consists of mechanical process by means of which the most outer part of a stone material is eroded, through the abrasive action of the jet of sand and air. This process is employed not only for the esterior cleaning of stone materials but also for the engraving of inscriptions and images on marble and stones. As already known, sandblasting presents a series of disadvantages.
  • a first problem of this process could be its abrasiveness, in which the removal of a superficial layer of the stone occurs.
  • the main object of the present invention is to solve the aforementioned problems of the cleaning methods for the surfaces of the stone materials. More particularly, object of the present invention is to supply a composition for the cleaning of stone material surfaces, which is not aggressive for the treated material and whose principle of action is not abrasive.
  • Another object of the present invention is to supply a high efficacy composition for the cleaning of stone material surfaces and whose use doesn't leave superficial rings or films at the end of the process.
  • Another object of the present invention is to supply a composition for the cleaning of stone material surfaces that could be employed for eliminating moulds, soot and encrustations deriving from smog and hydrocarbons.
  • An additional object of the present invention is to supply a composition for the cleaning of stone material surfaces, whose use allow the processed stone to reacquire the original natural appearance.
  • a further object of the present invention is to supply a composition for the cleaning of stone material surfaces which doesn't represent a risk for operators involved in its use. Accordingly, the use of the composition object of the present invention does not require the use of skilled workers.
  • Another object of the present invention is to supply a non-toxic and biodegradable composition for the cleaning of stone material surfaces which does not produce waste at the end of the treatment.
  • An additional object of the present invention is to supply a composition for the cleaning of stone material surfaces of natural or artificial origin, with high porosity and not, for example "travertine" marble, bush hammered stone, stone benches, statues, monuments and daunting historical buildings.
  • one last object of the present invention is to supply a composition for the cleaning of stone material surfaces whose implementation does not require special tools and has a reduced implementation time. Furthermore, the composition object of the present invention will show high retention time (more than 24 months) if rightly stored in sealed storage units and far from heat sources. In addition, the same composition can possibly be produced directly on site.
